摘要：Appointment systems are widely adopted in many service organizations. The simplest and most common format is the equally-spaced (ES) system, in which the inter-appointment times between consecutive arrivals are equal. One major drawback of such a system is the long expected waiting time for later arrivals, which makes later appointment positions unappealing to customers. As a result, customers who take these positions are more likely to abandon their appointments, leading to a higher no-show r...

摘要：We study the optimal supply chain design for a dual-channel retailer that operates physical and web-based stores and has traditionally managed each one separately. With increased pressures from customers and decreased profits due to marked-down leftover inventories in each channel, the retailer considers integrating the supply chain operations of both channels and using in-store inventory more effectively across different channels. In contrast to the existing literature, we focus on the firm's...

摘要：In current clinical practice, priority-specific wait time targets are usually determined based on the consensus of medical specialists and health care administrators. The rationale behind this approach considers clinical urgency but it does not consider the efficient use of clinical resources and the patient volume associated with each priority class. The approach we present here aims to determine wait time targets in a systematic fashion that both respects clinically acceptable maximum recomm...

摘要：Operations management (OM) in the public policy context is extremely complex with many mutually interacting factors characterized by feedback loops, delays and nonlinearities, as well as multiple stakeholders pursuing divergent objectives. Prior researchers have called for a systems approach in these contexts, arguing that standard OM methodologies such as mathematical programming, and queuing theory often cannot fully address these problems. Researchers have employed one such systems approach...

摘要：A downstream manufacturer can procure high-quality inputs from its upstream raw material supplier to produce finished products with high quality. The manufacturer may also have the option to source alternative cheaper low-quality inputs to partially replace the inputs from its supplier to produce finished products of lower quality. That is, the manufacturer can use a mixture of the supplier's inputs and alternative ones in product design such that product quality depends on the proportion of e...
